Abstract
A numerically controlled machining method and a numerically controlled machining system execute numerically controlled machining. An optimum processing tool is selected based on the numerical control orders, and the processing steps are optimized. A numerically controlled machining system is constituted by a numerically controlled processor, controllers and numerically controlled machines. The numerically controlled processor finds production times for machining parts for all the numerical control orders and compares them with a reference value to classify them into a group of special express processes and a group of normal processes. The special express processes pertain to the group of machining methods giving importance to the degree of finish, and the normal processes are divided into a group of machining methods for minimizing the exchange of machining tools or to a group of machining methods of optimizing a drawing number, whichever gives better machining efficiency. The numerically controlled processor further prepares numerical control machining data for each of the groups and distributes them to the controllers.
